Hi! I have done this minimalist program to calculate how much time will take to fill the mist energy tank. Installation not required. Just enter your current ME, press enter, then the current time (first hours, space, minutes) and then press enter again. It'll calculates the time and show you when it'll be ready.
To exit, press enter one more time.
There's a small bug that happens when you put a number bigger than 100, but I don't care about it.
its a really simple equation:
(100*13.2)-(current ME*13.2)
